I wonder if they are using the same (undocumented) exploit for each of these attacks.

I am certainly no expert in this field, but I would have thought discovering new exploits and security holes would take time, yet these guys are hitting several major sites a week.

From what I understand, their main tool is simple SQL injection.

Most websites seem to have at least one XSS or SQL injection hole. Nearly all have CSRF flaws.

Still, census data should not be accessible from a public facing web site. That's just amateur hour. You should really assume that anything with a POST form is vulnerable.

well its got to go in somehow, perhaps a facade that exposes only preparedstatements procs could have prevented this, but equally perhaps they exploited the facade, the transport mechanism to the facade, the db driver..... who knows, what is known is that theres a path, however narrow

No, they should have processed the data on a secure network, then burnt CDs with the final results.

That's how Australia treats important (Top Secret classified) data. I don't know how classified our census is, it should be treated with a bit of respect.

Agreed. Any submitted data should have been immediately encrypted with a public key who's companion private key was stored offline. It should have then been immediately transferred to a secondary box which was setup with a single function of accepting and storing the data. Ie a box which you can't query over the network for data.

As soon as the census closed, the relevant boxes should have been taken offline. The data moved to a "secure" location, and the original boxes wiped and destroyed.

Considering the data that was being collected, I don't think this is overkill.

For those who are interested, these are the questions: http://www.ons.gov.uk/census/2011-census/2011-census-questio...
